essential questions

1. how do nematodes effect the farmers crops?
2. if the crops are damaged how much does it cost the farmers?
3. how does the amount of money spent effect how much it costs in the stores?
4. if people know why the price is so high will they want to do something about it?
5. is there any way you can kill nematodes?

Effect of disturbances on trophic groups in soil nematode assemblages

In the passage “Effect of disturbances on trophic groups in soil nematode assemblages” the author Robert McSorley states that nematodes are abundant in soil ecosystems, where they have a variety of important function (Effect of disturbances). Plant parasites do not decompose the plants but they obtain food and energy directly from plant roots (effects of disturbances). Ni, Zn, Cu can reduce the number of omnivores and predators in soil. It makes short-term effects on them but if there are plants and if they can still feed they don’t go away. Soil fumigation is a way to get rid of nematodes. The bad thing about this is once the field is fumigated they will just move to some other part that has not been sprayed for them yet. The author is trying to tell us that there is no way to get rid of nematodes, we just slow them down. They cost so much for farmers and effects their crops greatly.

Lohr: Create your own future nematodes

In the passage “Lohr: create your own future nematodes” the author Keith Balderson states that nematodes have not effected corn but there are some indication that nematode populations are shifting and increasing and injury to corn may be increased (Lohr). The use of insecticides to seeds can actually increase the nematode population. There have been several samples that were found of sting nematodes, a species that can cause significant yield loss in sandy soils (Lohr).

Awareness of plant-parasitic nematodes

In the article “awareness of plant-parasitic nematodes” the authors Frank Kagoda, John Derera, Pangirayi Tongoona and, Daniel L. Coyne state that grain loss has been reported in maize from nematodes. In Kenya an estimated fifty percent yield loss was due to root-lesion nematodes. There is no germaplast that can eliminate nematodes from the soil (awareness of plant-parasitic nematodes). Even though this is happening many people do not know why this happens. They also state that farmers do now know what to look for on their crops to see if there is nematode damage. The authors have made this article to inform people about nematodes. If more people know about nematodes and how they affect crops and how much they cost farmers more people will know why the prices in the store are so high.
